When the touch screen is implemented as a capacitance type,the proximity sensor 141 can sense proximity of a pointer relative tothe touch screen by changes of an electromagnetic field, which isresponsive to an approach of an object with conductivity. In this case,the touch screen (touch sensor) may also be categorized as a proximitysensor.

The term “proximity touch” will often be referred to herein to denotethe scenario in which a pointer is positioned to be proximate to thetouch screen without contacting the touch screen. The term “contacttouch” will often be referred to herein to denote the scenario in whicha pointer makes physical contact with the touch screen. For the positioncorresponding to the proximity touch of the pointer relative to thetouch screen, such position will correspond to a position where thepointer is perpendicular to the touch screen. The proximity sensor 141may sense proximity touch, and proximity touch patterns (for example,distance, direction, speed, time, position, moving status, and thelike). In general, controller 180 processes data corresponding toproximity touches and proximity touch patterns sensed by the proximitysensor 141, and cause output of visual information on the touch screen.In addition, the controller 180 can control the mobile terminal 100 toexecute different operations or process different data (or information)according to whether a touch with respect to a point on the touch screenis either a proximity touch or a contact touch.

A touch sensor can sense a touch (or a touch input) applied to the touchscreen, such as display unit 151, using any of a variety of touchmethods. Examples of such touch methods include a resistive type, acapacitive type, an infrared type, and a magnetic field type, amongothers.

As one example, the touch sensor may be configured to convert changes ofpressure applied to a specific part of the display unit 151, or convertcapacitance occurring at a specific part of the display unit 151, intoelectric input signals. The touch sensor may also be configured to sensenot only a touched position and a touched region, but also touchpressure and/or touch capacitance. A touch object is generally used toapply a touch input to the touch sensor. Examples of typical touchobjects include a finger, a touch pen, a stylus pen, a pointer, or thelike.

When a touch input is sensed by a touch sensor, corresponding signalsmay be transmitted to a touch controller. The touch controller mayprocess the received signals, and then transmit corresponding data tothe controller 180. Accordingly, the controller 180 may sense whichregion of the display unit 151 has been touched. Here, the touchcontroller may be a component separate from the controller 180, thecontroller 180, and combinations thereof.

Meanwhile, the controller 180 may execute the same or different controlsaccording to a type of touch object that touches the touch screen or atouch key provided in addition to the touch screen. Whether to executethe same or different control according to the object which provides atouch input may be decided based on a current operating state of themobile terminal 100 or a currently executed application program, forexample.

The touch sensor and the proximity sensor may be implementedindividually, or in combination, to sense various types of touches. Suchtouches includes a short (or tap) touch, a long touch, a multi-touch, adrag touch, a flick touch, a pinch-in touch, a pinch-out touch, a swipetouch, a hovering touch, and the like.

If desired, an ultrasonic sensor may be implemented to recognizeposition information relating to a touch object using ultrasonic waves.The controller 180, for example, may calculate a position of a wavegeneration source based on information sensed by an illumination sensorand a plurality of ultrasonic sensors. Since light is much faster thanultrasonic waves, the time for which the light reaches the opticalsensor is much shorter than the time for which the ultrasonic wavereaches the ultrasonic sensor. The position of the wave generationsource may be calculated using this fact. For instance, the position ofthe wave generation source may be calculated using the time differencefrom the time that the ultrasonic wave reaches the sensor based on thelight as a reference signal.

The camera 121, which has been depicted as a component of the input unit120, typically includes at least one a camera sensor (CCD, CMOS etc.), aphoto sensor (or image sensors), and a laser sensor.

Implementing the camera 121 with a laser sensor may allow detection of atouch of a physical object with respect to a 3D stereoscopic image. Thephoto sensor may be laminated on, or overlapped with, the displaydevice. The photo sensor may be configured to scan movement of thephysical object in proximity to the touch screen. In more detail, thephoto sensor may include photo diodes and transistors at rows andcolumns to scan content received at the photo sensor using an electricalsignal which changes according to the quantity of applied light. Namely,the photo sensor may calculate the coordinates of the physical objectaccording to variation of light to thus obtain position information ofthe physical object.

The display unit 151 is generally configured to output informationprocessed in the mobile terminal 100. For example, the display unit 151may display execution screen information of an application programexecuting at the mobile terminal 100 or user interface (UI) and graphicuser interface (GUI) information in response to the execution screeninformation.

Also, the display unit 151 may be implemented as a stereoscopic displayunit for displaying stereoscopic images.

A typical stereoscopic display unit may employ a stereoscopic displayscheme such as a stereoscopic scheme (a glass scheme), anauto-stereoscopic scheme (glassless scheme), a projection scheme(holographic scheme), or the like.

The audio output module 152 is generally configured to output audiodata. Such audio data may be obtained from any of a number of differentsources, such that the audio data may be received from the wirelesscommunication unit 110 or may have been stored in the memory 170. Theaudio data may be output during modes such as a signal reception mode, acall mode, a record mode, a voice recognition mode, a broadcastreception mode, and the like. The audio output module 152 can provideaudible output related to a particular function (e.g., a call signalreception sound, a message reception sound, etc.) performed by themobile terminal 100. The audio output module 152 may also be implementedas a receiver, a speaker, a buzzer, or the like.

A haptic module 153 can be configured to generate various tactileeffects that a user feels, perceive, or otherwise experience. A typicalexample of a tactile effect generated by the haptic module 153 isvibration. The strength, pattern and the like of the vibration generatedby the haptic module 153 can be controlled by user selection or settingby the controller. For example, the haptic module 153 may outputdifferent vibrations in a combining manner or a sequential manner.

Besides vibration, the haptic module 153 can generate various othertactile effects, including an effect by stimulation such as a pinarrangement vertically moving to contact skin, a spray force or suctionforce of air through a jet orifice or a suction opening, a touch to theskin, a contact of an electrode, electrostatic force, an effect byreproducing the sense of cold and warmth using an element that canabsorb or generate heat, and the like.

The haptic module 153 can also be implemented to allow the user to feela tactile effect through a muscle sensation such as the user's fingersor arm, as well as transferring the tactile effect through directcontact. Two or more haptic modules 153 may be provided according to theparticular configuration of the mobile terminal 100.

An optical output module 154 can output a signal for indicating an eventgeneration using light of a light source. Examples of events generatedin the mobile terminal 100 may include message reception, call signalreception, a missed call, an alarm, a schedule alarm, an emailreception, information reception through an application, and the like.

A signal output by the optical output module 154 may be implemented insuch a manner that the mobile terminal emits monochromatic light orlight with a plurality of colors. The signal output may be terminated asthe mobile terminal senses that a user has checked the generated event,for example.

The interface unit 160 serves as an interface for external devices to beconnected with the mobile terminal 100. For example, the interface unit160 can receive data transmitted from an external device, receive powerto transfer to elements and components within the mobile terminal 100,or transmit internal data of the mobile terminal 100 to such externaldevice. The interface unit 160 may include wired or wireless headsetports, external power supply ports, wired or wireless data ports, memorycard ports, ports for connecting a device having an identificationmodule, audio input/output (I/O) ports, video I/O ports, earphone ports,or the like.

The identification module may be a chip that stores various informationfor authenticating authority of using the mobile terminal 100 and mayinclude a user identity module (UIM), a subscriber identity module(SIM), a universal subscriber identity module (USIM), and the like. Inaddition, the device having the identification module (also referred toherein as an “identifying device”) may take the form of a smart card.Accordingly, the identifying device can be connected with the terminal100 via the interface unit 160.

When the mobile terminal 100 is connected with an external cradle, theinterface unit 160 can serve as a passage to allow power from the cradleto be supplied to the mobile terminal 100 or may serve as a passage toallow various command signals input by the user from the cradle to betransferred to the mobile terminal there through. Various commandsignals or power input from the cradle may operate as signals forrecognizing that the mobile terminal is properly mounted on the cradle.

The memory 170 can store programs to support operations of thecontroller 180 and store input/output data (for example, phonebook,messages, still images, videos, etc.). The memory 170 may store datarelated to various patterns of vibrations and audio which are output inresponse to touch inputs on the touch screen.

The memory 170 may include one or more types of storage mediumsincluding a flash memory type, a hard disk type, a solid state disk(SSD) type, a silicon disk drive (SDD) type, a multimedia card microtype, a card-type memory (e.g., SD or DX memory, etc), a Random AccessMemory (RAM), a Static Random Access Memory (SRAM), a Read-Only Memory(ROM), an Electrically Erasable Programmable Read-Only Memory (EEPROM),a Programmable Read-Only memory (PROM), a magnetic memory, a magneticdisk, an optical disk, and the like. The mobile terminal 100 may also beoperated in relation to a network storage device that performs thestorage function of the memory 170 over a network, such as the Internet.

The controller 180 may typically control the general operations of themobile terminal 100 as well as operations associated with theapplication programs. For example, the controller 180 may set or releasea lock state for restricting a user from inputting a control commandwith respect to applications when a status of the mobile terminal meetsa preset condition.

The controller 180 can also perform the controlling and processingassociated with voice calls, data communications, video calls, and thelike, or perform pattern recognition processing to recognize ahandwriting input or a picture drawing input performed on the touchscreen as characters or images, respectively. In addition, thecontroller 180 can control one or a combination of those components inorder to implement various exemplary embodiments disclosed herein.

The power supply unit 190 receives external power or provide internalpower and supply the appropriate power required for operating respectiveelements and components included in the mobile terminal 100. The powersupply unit 190 may include a battery, which is typically rechargeableor be detachably coupled to the terminal body for charging.

The power supply unit 190 may include a connection port. The connectionport may be configured as one example of the interface unit 160 to whichan external charger for supplying power to recharge the battery iselectrically connected.

As another example, the power supply unit 190 may be configured torecharge the battery in a wireless manner without use of the connectionport. In this example, the power supply unit 190 can receive power,transferred from an external wireless power transmitter, using at leastone of an inductive coupling method which is based on magnetic inductionor a magnetic resonance coupling method which is based onelectromagnetic resonance.

Various embodiments described herein may be implemented in acomputer-readable medium, a machine-readable medium, or similar mediumusing, for example, software, hardware, or any combination thereof.

Referring now to FIGS. 1B and 1C, the mobile terminal 100 is describedwith reference to a bar-type terminal body. However, the mobile terminal100 may alternatively be implemented in any of a variety of differentconfigurations. Examples of such configurations include watch-type,clip-type, glasses-type, or as a folder-type, flip-type, slide-type,swing-type, and swivel-type in which two and more bodies are combinedwith each other in a relatively movable manner, and combinationsthereof. Discussion herein will often relate to a particular type ofmobile terminal (for example, bar-type, watch-type, glasses-type, andthe like). However, such teachings with regard to a particular type ofmobile terminal will generally apply to other types of mobile terminalsas well.

Here, considering the mobile terminal 100 as at least one set, theterminal body may be understood as a conception referring to the set.

The mobile terminal 100 will generally include a case (for example,frame, housing, cover, and the like) forming the appearance of theterminal. In this embodiment, the case is formed using a front case 101and a rear case 102. Various electronic components are incorporated intoa space formed between the front case 101 and the rear case 102. Atleast one middle case may be additionally positioned between the frontcase 101 and the rear case 102.

The display unit 151 is shown located on the front side of the terminalbody to output information. As illustrated, a window 151 a of thedisplay unit 151 may be mounted to the front case 101 to form the frontsurface of the terminal body together with the front case 101.

In some embodiments, electronic components may also be mounted to therear case 102. Examples of such electronic components include adetachable battery 191, an identification module, a memory card, and thelike. Rear cover 103 is shown covering the electronic components, andthis cover may be detachably coupled to the rear case 102. Therefore,when the rear cover 103 is detached from the rear case 102, theelectronic components mounted to the rear case 102 are externallyexposed.

As illustrated, when the rear cover 103 is coupled to the rear case 102,a side surface of the rear case 102 is partially exposed. In some cases,upon the coupling, the rear case 102 may also be completely shielded bythe rear cover 103. In some embodiments, the rear cover 103 may includean opening for externally exposing a camera 121 b or an audio outputmodule 152 b.

The cases 101, 102, 103 may be formed by injection-molding syntheticresin or may be formed of a metal, for example, stainless steel (STS),aluminum (Al), titanium (Ti), or the like.

As an alternative to the example in which the plurality of cases form aninner space for accommodating components, the mobile terminal 100 may beconfigured such that one case forms the inner space. In this example, amobile terminal 100 having a uni-body is formed in such a manner thatsynthetic resin or metal extends from a side surface to a rear surface.

If desired, the mobile terminal 100 may include a waterproofing unit(not shown) for preventing introduction of water into the terminal body.For example, the waterproofing unit may include a waterproofing memberwhich is located between the window 151 a and the front case 101,between the front case 101 and the rear case 102, or between the rearcase 102 and the rear cover 103, to hermetically seal an inner spacewhen those cases are coupled.

The mobile terminal 100 may include a display unit 151, first and secondaudio output module 152 a and 152 b, a proximity sensor 141, anillumination sensor 142, an optical output module 154, first and secondcameras 121 a and 121 b, first and second manipulation units 123 a and123 b, a microphone 122, an interface unit 160, and the like.

Hereinafter, as illustrated in FIGS. 1B and 1C, description will begiven of the exemplary mobile terminal 100 in which the front surface ofthe terminal body is shown having the display unit 151, the first audiooutput module 152 a, the proximity sensor 141, the illumination sensor142, the optical output module 154, the first camera 121 a, and thefirst manipulation unit 123 a, the side surface of the terminal body isshown having the second manipulation unit 123 b, the microphone 122, andthe interface unit 160, and the rear surface of the terminal body isshown having the second audio output module 152 b and the second camera121 b.

However, those components may not be limited to the arrangement. Somecomponents may be omitted or rearranged or located on differentsurfaces. For example, the first manipulation unit 123 a may be locatedon another surface of the terminal body, and the second audio outputmodule 152 b may be located on the side surface of the terminal bodyother than the rear surface of the terminal body.

The display unit 151 outputs information processed in the mobileterminal 100. For example, the display unit 151 may display executionscreen information of an application program executing at the mobileterminal 100 or user interface (UI) and graphic user interface (GUI)information in response to the execution screen information.

The display unit 151 may be implemented using one or more suitabledisplay devices. Examples of such suitable display devices include aliquid crystal display (LCD), a thin film transistor-liquid crystaldisplay (TFT-LCD), an organic light emitting diode (OLED), a flexibledisplay, a 3-dimensional (3D) display, an e-ink display, andcombinations thereof.

The display unit 151 may be implemented using two display devices, whichcan implement the same or different display technology. For instance, aplurality of the display units 151 may be arranged on one side, eitherspaced apart from each other, or these devices may be integrated, orthese devices may be arranged on different surfaces.

The display unit 151 may also include a touch sensor which senses atouch input received at the display unit. When a touch is input to thedisplay unit 151, the touch sensor may be configured to sense this touchand the controller 180, for example, may generate a control command orother signal corresponding to the touch. The content which is input inthe touching manner may be a text or numerical value, or a menu itemwhich can be indicated or designated in various modes.

The touch sensor may be configured in a form of a film having a touchpattern, disposed between the window 151 a and a display on a rearsurface of the window 151 a, or a metal wire which is patterned directlyon the rear surface of the window 151 a. Alternatively, the touch sensormay be integrally formed with the display. For example, the touch sensormay be disposed on a substrate of the display or within the display.

The display unit 151 may also form a touch screen together with thetouch sensor. Here, the touch screen may serve as the user input unit123 (see FIG. 1A). Therefore, the touch screen may replace at least someof the functions of the first manipulation unit 123 a.

The first audio output module 152 a may be implemented in the form of areceiver for transferring call sounds to a user's ear and the secondaudio output module 152 b may be implemented in the form of a loudspeaker to output alarm sounds, multimedia audio reproduction, and thelike.

The window 151 a of the display unit 151 will typically include anaperture to permit audio generated by the first audio output module 152a to pass. One alternative is to allow audio to be released along anassembly gap between the structural bodies (for example, a gap betweenthe window 151 a and the front case 101). In this case, a holeindependently formed to output audio sounds may not be seen or isotherwise hidden in terms of appearance, thereby further simplifying theappearance and manufacturing of the mobile terminal 100.

The optical output module 154 can be configured to output light forindicating an event generation. Examples of such events include amessage reception, a call signal reception, a missed call, an alarm, aschedule alarm, an email reception, information reception through anapplication, and the like. When a user has checked a generated event,the controller 180 can control the optical output module 154 to stop thelight output.

The first camera 121 a can process image frames such as still or movingimages obtained by the image sensor in a capture mode or a video callmode. The processed image frames can then be displayed on the displayunit 151 or stored in the memory 170.

The first and second manipulation units 123 a and 123 b are examples ofthe user input unit 123, which may be manipulated by a user to provideinput to the mobile terminal 100. The first and second manipulationunits 123 a and 123 b may also be commonly referred to as a manipulatingportion, and may employ any tactile method that allows the user toperform manipulation such as touch, push, scroll, or the like. The firstand second manipulation units 123 a and 123 b may also employ anynon-tactile method that allows the user to perform manipulation such asproximity touch, hovering, or the like.

FIG. 1B illustrates the first manipulation unit 123 a as a touch key,but possible alternatives include a mechanical key, a push key, a touchkey, and combinations thereof.

Input received at the first and second manipulation units 123 a and 123b may be used in various ways. For example, the first manipulation unit123 a may be used by the user to provide an input to a menu, home key,cancel, search, or the like, and the second manipulation unit 123 b maybe used by the user to provide an input to control a volume level beingoutput from the first or second audio output modules 152 a or 152 b, toswitch to a touch recognition mode of the display unit 151, or the like.

As another example of the user input unit 123, a rear input unit (notshown) may be located on the rear surface of the terminal body. The rearinput unit can be manipulated by a user to provide input to the mobileterminal 100. The input may be used in a variety of different ways. Forexample, the rear input unit may be used by the user to provide an inputfor power on/off, start, end, scroll, control volume level being outputfrom the first or second audio output modules 152 a or 152 b, switch toa touch recognition mode of the display unit 151, and the like. The rearinput unit may be configured to permit touch input, a push input, orcombinations thereof.

The rear input unit may be located to overlap the display unit 151 ofthe front side in a thickness direction of the terminal body. As oneexample, the rear input unit may be located on an upper end portion ofthe rear side of the terminal body such that a user can easilymanipulate it using a forefinger when the user grabs the terminal bodywith one hand. Alternatively, the rear input unit can be positioned atmost any location of the rear side of the terminal body.

Embodiments that include the rear input unit may implement some or allof the functionality of the first manipulation unit 123 a in the rearinput unit. As such, in situations where the first manipulation unit 123a is omitted from the front side due to the touch screen or rear inputunit replacing at least some functions of the first manipulation unit123 a provided on the front of the terminal body, the display unit 151can have a larger screen.

As a further alternative, the mobile terminal 100 may include a fingerscan sensor which scans a user's fingerprint. The controller 180 canthen use fingerprint information sensed by the finger scan sensor aspart of an authentication procedure. The finger scan sensor may also beinstalled in the display unit 151 or implemented in the user input unit123.

The microphone 122 is shown located at an end of the mobile terminal100, but other locations are possible. If desired, multiple microphonesmay be implemented, with such an arrangement permitting the receiving ofstereo sounds.

The interface unit 160 may serve as a path allowing the mobile terminal100 to interface with external devices. For example, the interface unit160 may include one or more of a connection terminal for connecting toanother device (for example, an earphone, an external speaker, or thelike), a port for near field communication (for example, an InfraredData Association (IrDA) port, a Bluetooth port, a wireless LAN port, andthe like), or a power supply terminal for supplying power to the mobileterminal 100. The interface unit 160 may be implemented in the form of asocket for accommodating an external card, such as SubscriberIdentification Module (SIM), User Identity Module (UIM), or a memorycard for information storage.

The second camera 121 b is shown located at the rear side of theterminal body and includes an image capturing direction that issubstantially opposite to the image capturing direction of the firstcamera unit 121 a.

The second camera 121 b can include a plurality of lenses arranged alongat least one line. The plurality of lenses may also be arranged in amatrix configuration. The cameras may be referred to as an “arraycamera.” When the second camera 121 b is implemented as an array camera,images may be captured in various manners using the plurality of lensesand images with better qualities.

A flash 124 is shown adjacent to the second camera 121 b. When an imageof a subject is captured with the camera 121 b, the flash 124 mayilluminate the subject.

The second audio output module 152 b can be located on the terminalbody. The second audio output module 152 b may implement stereophonicsound functions in conjunction with the first audio output module 152 a,and may be also used for implementing a speaker phone mode for callcommunication.

At least one antenna for wireless communication may be located on theterminal body. The antenna may be installed in the terminal body orformed by the case. For example, an antenna which configures a part ofthe broadcast receiving module 111 may be retractable into the terminalbody. Alternatively, an antenna may be formed using a film attached toan inner surface of the rear cover 103, or a case that includes aconductive material.

A power supply unit 190 for supplying power to the mobile terminal 100may include a battery 191, which is mounted in the terminal body ordetachably coupled to an outside of the terminal body.

The battery 191 may receive power via a power source cable connected tothe interface unit 160. Also, the battery 191 can be recharged in awireless manner using a wireless charger. Wireless charging may beimplemented by magnetic induction or electromagnetic resonance.

The rear cover 103 is shown coupled to the rear case 102 for shieldingthe battery 191, to prevent separation of the battery 191, and toprotect the battery 191 from an external impact or from foreignmaterial. When the battery 191 is detachable from the terminal body, therear case 103 may be detachably coupled to the rear case 102.

An accessory for protecting an appearance or assisting or extending thefunctions of the mobile terminal 100 can also be provided on the mobileterminal 100. As one example of an accessory, a cover or pouch forcovering or accommodating at least one surface of the mobile terminal100 may be provided. The cover or pouch may cooperate with the displayunit 151 to extend the function of the mobile terminal 100. Anotherexample of the accessory is a touch pen for assisting or extending atouch input to a touch screen.

Hereinafter, description will be given of exemplary embodimentsassociated with a control method which can be implemented in the mobileterminal having such configuration, with reference to the accompanyingdrawings. It will be obvious to those skilled in the art that thepresent disclosure can be specified into other particular forms withoutdeparting from the spirit and essential characteristics of the presentdisclosure.

FIG. 2 is a conceptual view illustrating operations implementedaccording to the present invention.

As illustrated in FIG. 2, a display unit 251 is provided with a firstregion A located on a front surface of a terminal main body, and asecond region B extending from the first region A and located on sidesurfaces of the main body. The first region A and the second region Bdiffer from each other in a type of information displayed. The firstregion A and the second region B are divided according to differenttypes of user graphic interfaces (GUIs) provided thereto, respectively.

Also, the second region B is provided with a left-sided region B1 and aright-sided region B2 located at left and right side surfaces of theterminal, respectively. The second region B has a left-right symmetricstructure based on the first region A.

Referring to FIG. 2A, a home screen page may be output on the displayunit 251 of the mobile terminal. The home screen page may include atleast one object. The object may be an icon of an application installedin the mobile terminal or a widget. Here, the home screen page may beoutput over the first and second regions A and B, but the presentinvention may not be limited to this. For example, the home screen pagemay be output only on the first region A, and the second region may be atarget area to which a touch input is applied without an output ofinformation.

Referring to FIG. 2B, the controller senses a touch input when the touchinput is applied to the second region B, and executes a controloperation associated with the touch input. In this example, when a touchinput is applied to a notification icon I notifying an event generation,information related to the event is output on the first region A.

Such operations associated with the touch onto the side surfaces shouldbe supported by hardware. Hereinafter, the hardware configuration of theterminal performing the operations of FIG. 2 will be described in moredetail. The present invention also provides a structure of implementingthe operations in hardware as well as implementing a larger screen byreducing a size of bezel.

FIG. 3A is a front perspective view illustrating one example of a mobileterminal in accordance with the present invention, and FIG. 3B is a rearperspective view of the mobile terminal illustrated in FIG. 3A.

A mobile terminal 200 is described with reference to a bar-type terminalbody. However, the mobile terminal 200 may alternatively be implementedin any of a variety of different configurations. Examples of suchconfigurations include slide-type, folder-type, swing-type, andswivel-type in which two and more bodies are combined with each other ina relatively movable manner, and combinations thereof.

The mobile terminal 200 generally includes a case (for example, frame,housing, cover, and the like) forming the appearance of the terminal. Inthis embodiment, the case may be divided into a front case 201 and arear case 202 (see FIGS. 3A and 3B). Various electronic components areincorporated into a space formed between the front case 201 and the rearcase 202. At least one middle case may be additionally positionedbetween the front case 201 and the rear case 202.

The terminal body, generally the front case 201 is shown having adisplay unit 251, an audio output module 252, a camera module 221 andthe like. An interface 270 and the like may be disposed on side surfacesof the front case 201 and the rear case 202.

The display unit 251 occupies most of a main surface of the front case201. That is, the display unit 251 is disposed on the front surface ofthe terminal to display visual information. The display unit 251disclosed herein is configured in the form of extending up to anothersurface of the terminal in addition to the front surface of theterminal. In more detail, the display unit 251 is provided with a firstregion A located on the front surface, and a second region B (see FIG.2) extending from the first region A and located on the side surfaces ofthe main body.

For example, a window which is disposed on an upper surface of thedisplay unit 251 is configured in a manner that both side surfacesthereof are curved. Accordingly, the appearance of the front surface andthe side surface of the terminal body is defined by the window.Therefore, the first region 261 and the second region 262 may beconnected without a physical boundary therebetween. Here, the displayunit 251 may be provided with a display device which is formed in acurved shape and embedded to correspond to the window.

As another example, the display unit 251 may be a flexible display. Theflexible display refers to a display which is curved, bent, twisted,folded, or rolled by an external force. Here, the flexible display unitmay include both a general flexible display and an electronic paper.

The typical flexible display is generally formed as a lightweight,non-fragile display, which still exhibits characteristics of aconventional flat panel display, but is instead fabricated on a thinflexible substrate which can be curved, bent, folded, or rolled, like apaper.

The term e-paper refers to a display technology employing thecharacteristic of a general ink, and is different from the conventionalflat panel display in view of using reflected light. E-paper isgenerally understood as changing pictures or text using a twist ball orvia electrophoresis using a capsule.

According to the characteristic of the flexible material, a terminalmain body in which both side surfaces of the display unit are curved maybe configured.

The audio output module 252 and the camera module 221 may be disposed ona region adjacent to one of both end portions of the display unit 251,and a front input unit (not illustrated) and a microphone 222 may bedisposed on a region adjacent to the other end portion.

The front input unit is an example of a user input unit 230 (see FIG.1), which may include a plurality of manipulation units. Themanipulation units may be referred to as a manipulating portion, and mayemploy any tactile method that allows the user to perform manipulationwith applying a tactile feeling.

Also, the display unit 251 may form a touch screen along with a touchsensor, and in this case, the touch screen may be a user input unit.This may allow for employing a configuration without a front input uniton the front surface of the terminal. That is, the first region 252 maybe the only one input unit located on the front surface of the terminal.

Referring to FIG. 3B, the rear surface of the terminal body, namely, therear case 202 may be further provided with a camera module 221′. Thecamera module 221′ may have an image capturing direction that issubstantially opposite to the image capturing direction of the cameramodule 221 (see FIG. 3A), and have different pixels from the cameramodule 221.

For example, the camera module 221 has a smaller number of pixels tocapture an image of the user's face and transmits such image to anotherparty, and the camera module 221′ has a larger number of pixels tocapture an image of a general object and not immediately transmits it inmost cases. The first and the second camera modules 221 and 221′ may beinstalled on the terminal body such that they can be rotatable or poppedup.

A flash and a mirror may be additionally disposed adjacent to the cameramodule 221′. When an image of a subject is captured with the cameramodule 221′, the flash may illuminate the subject. The mirror may allowthe user to see himself or herself when he or she wants to capture hisor her own image (i.e., self-image capturing) by using the camera module221′.

An audio output unit (not illustrated) may be further disposed on therear surface of the terminal body. The rear audio output module mayimplement stereophonic sound functions in conjunction with the frontaudio output module 252 (refer to FIG. 3A), and may be also used forimplementing a speaker phone mode for call communication.

That is, the front audio output module 252 (first audio output module)configured as a receiver may be located on the front surface of theterminal, and the second audio output module configured as a speaker maybe located on the rear surface. However, the present disclosure may notbe limited to this, and the second audio output module may be providedon the side surface of the terminal.

The terminal body is provided with a power supply unit for supplyingpower to the mobile terminal 200. The power supply unit 290 may beembedded in the terminal body or detachably coupled to an outside of theterminal body.

As illustrated, a rear input unit 232 may be disposed on the rearsurface of the terminal body. The rear input unit 232, for example, maybe located below the camera module 221′.

The rear input unit 232 can be manipulated by a user to provide input ofa command for controlling an operation of the mobile terminal 200. Theinput may be used in a variety of different ways. For example, the rearinput unit 232 may be manipulated by the user to input commands such aspower on/off, start, end, scroll, and command such as a control of avolume level output from the audio output module 252, switching of atouch recognition mode of the display unit 251, and the like. Thepresent disclosure, however, may not be limited to this, and theterminal may include one or both of the front input unit and the rearinput unit 232.

FIG. 4 is a partial sectional view of a mobile terminal having a displaymodule. As illustrated in FIG. 4, a display 330, a touch sensor 320 anda window 310 are provided on a frame 340. The frame, 340, the display330, the touch sensor 320 and the window 310 may all be curved towardside surfaces of the main body. Here, a bezel by the display 330 of themobile terminal is as thin as corresponding approximately to a thicknessof the window 310.

The bezel may have the least size when the window 310 is curved (bent)by 90°, in case where the window 310 is curved with a radius ofcurvature R at a point 0 located within the terminal. However, there isa case where the window 310 fails to be curved by 90° due to a processproblem. That is, there is a case where an angle α illustrated in FIG. 4is smaller than 90°.

For example, when curved by 90°, the window 310 is likely to be broken.As such, if the window 310 fails to be curved by 90°, the window 310should first be curved as much as possible and then the rest portion,namely, a portion corresponding to D in FIG. 4 should be formed by usinganother member, other than the window 310. Even in this instance, glassmay also be used but there is still a problem that the glass has to bebonded to the window 310. Therefore, one embodiment disclosed hereinwill be given limitedly of an example using another member, other thanthe glass. Here, the portion D may correspond to a side bezel where anyimage is not displayed when the mobile terminal is viewed in a lateraldirection, but the side bezel has no relationship to a bezel when themobile terminal is viewed in a front direction. So, detailed descriptionwill be omitted.

FIG. 5 is an exploded perspective view of a mobile terminal 300 inaccordance with a first exemplary embodiment disclosed herein, FIG. 6 isa partially-exploded perspective view of FIG. 5, and FIG. 7 is asectional view taken along the lines AA, BB and CC of FIG. 5.Hereinafter, the first exemplary embodiment disclosed herein will bedescribed with reference to FIGS. 5 to 7.

A mobile terminal 300 in accordance with a first exemplary embodimentdisclosed herein may include a main body having front and side surfaces,a window 310 disposed on a top of the main body and curved (or bent)from the front surface to one point of each side surface so as to defineat least part of each side surface, a touch sensor 320 disposed on arear surface of the window 310 and curved along the shape of the window310, a display 330 disposed on a rear surface of the touch sensor 320and curved along the shape of the touch sensor 320, a frame 340 disposedon a rear surface of the display 330 and having a shape corresponding tothe display 330 to support the display 330, and supporters to supportends of the window 310, the touch sensor 320 and the display 330. Also,a rear surface of the main body is covered with a rear case 380.

Here, the touch sensor 320 and the display 330, as illustrated in FIG.7, are longer or wider than the window 310 by an externally-exposedregion thereof. That is, the touch sensor 320 and the display 330 areformed longer than the window 310 by the portion D, as illustrated in asupporting member 370 of FIG. 4.

The above structure is similarly employed in second to fourth exemplaryembodiments to be explained later. Specifically, the touch sensor 320and the display unit 330 are formed longer than the window 310, suchthat a region longer than the display 310 can be externally exposedbefore the touch sensor 320 and the display 330 are coupled. Here, thewindow 310 which is shorter than the touch sensor 320 and the display330 is supported by the supporter so as to be stably coupled.

The frame 340 according to the first exemplary embodiment disclosedherein, as illustrated in FIG. 6, includes a front surface portion 341facing the front surface and forming a flat or curved surface, and sidesurface portions 342 each extending from the front surface portion 341and curved toward the side surface of the main body. The side surfaceportion 342 may be formed to be almost perpendicular to the frontsurface portion 341, and a curved section of the side surface portion342, unlike the window 310, can exceed 90°.

Here, the touch sensor 320 and the display 330 are curved to correspondto a curved shape of the window 310. When the front surface portion 341of the frame 340 is curved, the display 330, the touch sensor 320 andthe window 310 are curved accordingly. A printed circuit board 350 isdisposed below the frame 340 to perform a function of the controller180.

The first exemplary embodiment includes the supporting members 370 forsupporting the window 310. The supporting members 370 also support thetouch sensor 320 and the display 330 as well as the window 310, and arelocated between the frame 340 and the rear case 380. Each of thesupporting members 370 includes a vertical portion 371 that is locatedbelow the window 310 to come in contact with a lower end portion of thewindow 310 for support, and a horizontal portion 372 which is formedperpendicular to the vertical portion 371 to support the touch sensor320 and the display 330. The horizontal portion 372 may be provided witha plurality of through holes 373 which face a top. Each of the throughholes 373 is configured such that both of a first protrusion 343protruding from a lower end of the frame 340 and a second protrusion 381protruding from an edge of the upper surface of the rear case 380 areinserted therein.

In such a manner, the frame 340 and the rear case 380 may be engagedwith the supporting members 370 in a manner that the first protrusion343 and the second protrusion 381 are simultaneously inserted into onethrough hole 373 and are fixed in a closely-adhered state. FIG. 7Billustrates that the first protrusion 343 is formed more outside and thesecond protrusion 381 is formed more inside, but the present inventionmay not be limited to this. The first protrusion 343 may also be formedmore inside.

FIG. 7A illustrates that the vertical portion 371 of the supportingmember 370 comes in contact with the window 310, and the touch sensor320, the display unit 330 and the frame 340 are mounted on thehorizontal portion 372. FIG. 7B illustrates that the first protrusion343 formed on the lower end of the frame 340 and the second protrusion381 protruding from the upper surface of the rear case 380 are insertedinto the through hole 373. The first protrusion 343 is formed to havethe same height as the through hole 373 formed at the horizontal portion372.

Here, the supporting member 370 partially defines the appearance of themobile terminal 300. Thus, the supporting member 370 may have a smoothlycurved surface from a portion contacting the window 310 to a portioncontacting the rear case 380. That is, that the vertical portion 371 andthe horizontal portion 372 are perpendicular to each other merelyindicates that portions thereof forming a space for mounting the touchsensor 320, the display 330 and the frame 340 are approximatelyperpendicular to each other, but does not indicate that the entiresupporting member 370 is exactly formed in the perpendicular shape.

Here, a portion which is formed longer than the display 330 in FIG. 7Bcorresponds to the first protrusion 343. Also, a battery 390 is disposedbeneath the rear case 380 to cover the rear surface of the main body.This will be equally applied to battery covers 490 and 590 according tothe second and third exemplary embodiments to be explained later.

Here, the window 310, the touch sensor 320 and the display 330 may beintegrally formed into a single display module 301.

FIG. 8 is an exploded perspective view of a mobile terminal 400 inaccordance with a second exemplary embodiment disclosed herein, FIG. 9is a partially-exploded perspective view of FIG. 8, and FIG. 10 is asectional view taken along the lines AA, BB and CC of FIG. 8.Hereinafter, the second exemplary embodiment disclosed herein will bedescribed with reference to FIGS. 8 to 10. Repetitive description of thesame/like configurations to the first exemplary embodiment will beomitted.

As illustrated in FIGS. 8 to 10, a window 410, a touch sensor 420 and adisplay 430, similar to the first embodiment, are curved at sidesurfaces of the terminal. This is also similar to a frame 440. That is,the display 430, the touch sensor 420 and the window 410 disposed on theframe 440 are curved toward the side surfaces in a corresponding shape,similar to the first embodiment. Also, the window 410, the touch sensor420 and the display 430 may be integrally formed into a single displaymodule 401.

Here, the first exemplary embodiment has illustrated that the supportingmembers 370 support the touch sensor 320, the display 330 and the frame340 as well as the window 310. However, the second exemplary embodimentemploys mold members 415, instead of the supporting members 370. Themold members 415 may be formed on lower ends of the window 410 in alengthwise direction of the mobile terminal 400 through aninsert-injection molding operation. As illustrated in FIGS. 10A and 10B,the mold member 415 is as high as a portion at which the window 410 isformed shorter than the display 430.

In the second exemplary embodiment, the mold member 415 may correspondto the vertical portion 371 of the supporting member 370 of the firstexemplary embodiment.

In addition, in the second exemplary embodiment, the frame 440 furtherincludes an edge portion 443 that protrudes from a lower end of the sidesurface portion 442 in a horizontal direction. The edge portion 443 isformed in a flat shape such that the mold member 415, the touch sensor420 and the display 430 are flush with one another. However, the presentinvention may not be limited to this. As illustrated in a thirdexemplary embodiment to be explained later, a portion coming in contactwith the mold member 415 may more protrude such that the touch sensor420 and the display 430 can be fixedly inserted more stably.

As illustrated in FIGS. 10A and 10B, the mold member 415, the touchsensor 420 and the display 430 are mounted on the edge portion 443. Athird protrusion 481 protrudes from an edge of an upper surface of therear case 480 and comes in contact with an inner side surface of theframe 440. That is, the third protrusion 481 closely comes in contactwith an inner side of the side surface portion 442 of the frame 440, andthus the frame 440 is firmly fixed to a rear case 480.

In the second exemplary embodiment, the mold member 415 may bemodularized with the window 410 at the side end of the window 410through the insert-injection molding operation. In addition, the window410, the mold member 415, the touch sensor 420 and the display 430 maybe integrated into a single module. Here, a printed circuit board 450,as similar to the first exemplary embodiment, is located between theframe 440 and the rear case 480.

Here, the frame 440 may extend down to a lower end portion of the sidesurface of the main body, and the rear surface of the frame 440 may becovered with the rear case 480 and the battery cover 490.

For example, a first hook 616 is formed on the main surface portion 615b of the decoration member 615, and a first hole 646 is formed on thefront surface portion 341 (see FIG. 4) of the frame 640. The first hook616 is then fixedly inserted into the first hole 646, to tightly securethe touch sensor 620 and the display 630 between the decoration member615 and the frame 640.

A second hook 617 is formed on the curved portion 615 b of thedecoration member 615, and a second hole 647 is formed on the sidesurface portion 342 (see FIG. 4) of the frame 640. The second hook 617is fixedly inserted into the second hole 647, to prevent the curvedportion 615 b from being detached. That is, the first hook 616 is usedfor the purpose of preventing a movement of the decoration member 615 inthe Z-axial direction, and the second hook 617 is used for the purposeof preventing the detachment of the decoration member 615 in the X-axialdirection.

Also, those drawings illustrate that the decoration member 615 islocated at a lower end of the mobile terminal 600, but may also beprovided at an upper end of the mobile terminal, if necessary. Here, thedecoration member 615 may be made of polycarbonate (PC), and generallyused for shielding a lower bezel of the mobile terminal 600. A bezel inone exemplary embodiment refers to a region on which an image signal isnot output of an entire region of the mobile terminal 600. The bezel isgenerally formed by a circuit (including a printed circuit board and aflexible printed circuit board) for driving the mobile terminal 600 or acase.

Meanwhile, FIG. 19A is a view of the mobile terminal 600, viewed in theZ-axial direction. The curved portion 615 b of the decoration member 615is formed with a curvature R1 on an XY plane. In one exemplaryembodiment, the decoration member 615 is disposed on the lower bezel andhas corner portions curved. That is, in the front view of the mobileterminal 600, as illustrated in FIG. 19A, four corners have a uniformradius R1. The one embodiment disclosed herein proposes a form that thedecoration member 615 and the rear case 680 are coupled to each other.

Also, FIG. 19B is a view of the mobile terminal 600, viewed in theX-axial direction, and FIG. 19C is a view of the mobile terminal 600,viewed in the Y-axial direction. The decoration member 615 has acurvature R2 on an YZ plane, and a curvature R3 on a ZX plane. As such,the decoration member 615 is three-dimensionally formed with thepredetermined curvatures.

The decoration member 615 with the curvatures, as illustrated in FIG.16, is disposed on the touch sensor 620, and the printed circuit board650 is disposed between the frame 640 and the rear case 680. Also, therear case 680 also includes a wide and flat cover portion 684 that isformed at one side of the accommodating portion 685 to cover the rearsurface of the main body.

As illustrated in FIGS. 18A and 18B, the touchsensor 620 and the display 630 are formed longer than the window 610 ina lengthwise direction (i.e., the Y-axial direction in FIG. 14) of themain body of the terminal.

As aforementioned, the decoration member 615 is curved with thepredetermined curvatures R1, R2 and R3 on the XY, YZ and ZX planes. Inorder to mount the decoration member 615 with the three-dimensionalcurvatures on the rear case 680, cutout portions 625 and 635 (see FIG.16) are formed at end portions of the touch sensor 620 and the display630, respectively, in one exemplary embodiment disclosed herein. Eachend portion with the cutout portion 625 and 635 of the touch sensor 620and the display 630 corresponds to the curved portion 615 b and asection from the curved portion 615 b to one point of the main surfaceportion 615 a. The cutout portions may also fully meet the purpose ofthe present invention as long as they are formed at side end portions ofthe touch sensor 620 and the display 630.

Since the curved portion 615 b of the decoration member 615 has thethree-dimensional curvatures along the X-axial, Y-axial and Z-axialdirections, when the touch sensor 620 and the display 630 extend up to aregion D2 illustrated in FIGS. 18A and 18B without the cutout portions625 and 635, a starting point that the decoration member 615 is curvedshould be moved to the left side of a boundary between the window 610and the decoration member 615 in FIGS. 18A and 18B, and accordingly thedecoration member 615 should have a more increased width D1.

For example, as illustrated in FIG. 19A, the curved portion 615 b shouldbe inwardly curved with a predetermined curvature, starting from theboundary between the window 610 and the decoration member 615 within theXY plane. However, the curved portion 615 b cannot be inwardly curved ifthe cutout portions 625 and 635 are not formed. That is, the cutoutportions 625 and 635 may result in ensuring a space in which the curvedportion 615 b can be curved.

If the decoration member 615 increases in width, the lower bezel of themobile terminal 600 increases in size. To prevent this in the oneexemplary embodiment, as illustrated in FIG. 16, the cutout portions 625and 635 are formed at the touch sensor 620 and the display 630. Theformation of the cutout portions 625 and 635 may allow the curvedportion 615 b of the decoration member 615 to have the curvatures in thethree-dimensional manner, without moving the starting point that thedecoration member 615 is curved to the left side of the boundary betweenthe window 610 and the decoration member 615 in FIGS. 18A and 18B. Thatis, the curved portion 615 b of the decoration member 615 can be curvedin the X-axial, Y-axial and Z-axial directions at the boundary betweenthe window 610 and the decoration member 615. This may result inpreventing an increase in the size of the lower bezel of the mobileterminal and simultaneously providing an attractive design.

The corner structure for reducing the lower bezel has been described,which will equally be applied to an upper bezel. That is, the decorationmember 615 which is disposed on an upper end of the mobile terminal andmounted on the bottom surface portion 681 and the curved surface portion682 may be formed. Here, the upper bezel, similar to the lower bezel,can be reduced in size.

Also, when the window 610 located on the top of the mobile terminal isconfigured to be curved with three-dimensional curvatures, similar tothe curved portion 615 b of the decoration member 615, and the cutoutportions 625 and 635 are formed at the touch sensor 620 and the display630, the upper bezel of the mobile terminal, similar to theaforementioned lower bezel, can be reduced in size.

In such a manner, according to one embodiment disclosed herein, thelower or upper bezel can be minimized in size. Here, since thedecoration member 615 is a portion where image information cannot beoutput, the first manipulation unit 123 a should be located within theregion of the display 630.

Meanwhile, the cutout portions 625 and 635 may also be formed at atleast a part of the region D2, or at least a part of a region D3.

Here, D1 refers to the width of the decoration member 615, and alsocorresponds to the size of the lower bezel of the mobile terminal 600.D2 refers to a region where the touch sensor 620 and the display 630 areformed longer than the window 610, and D3 refers to a stepped portion ofthe display 630, as illustrated in FIGS. 18A and 18B.

Here, when the cutout portions 625 and 635 are formed near the boundarybetween the decoration member 615 and the window 610, it is difficult toachieve the purpose for fixing the touch sensor 620 and the display 630by the first hook 616. Therefore, the cutout portions 625 and 635 arepreferably formed at a part of the region D3.

That is, the decoration member 615 should be located on the uppersurface of the touch sensor 620.

As illustrated in FIG. 20, the rear case 680 includes a sidewall portion683 that is brought into contact with a window 610, and an accommodatingportion 685 that is formed at an inner side of the sidewall portion 683and accommodates a touch sensor 620 and a display 630 therein. Theaccommodating portion 685 is more recessed than the other portion of therear case 680 such that the touch sensor 620 and the display 630 can beeasily accommodated therein. Meanwhile, referring to FIG. 16, the rearcase 680 includes a bottom surface portion 681 that perpendicularlyextends from the sidewall portion 683 and is higher than the sidewallportion 683, and a curved surface portion 682 that is curved to connectthe bottom surface portion 681 and the sidewall portion 683 to eachother.

Meanwhile, a decoration member 615 which has the same thickness as thewindow 610 is further provided at one side of the window 610, such thatthe bottom surface portion 681 and the curved surface portion 682 aremounted thereon. The decoration member 615 includes a main surfaceportion 615 a that is formed on a front surface thereof and occupiesmost of the front surface, and a curved portion 615 b that extends fromthe main surface portion 615 a and is curved to be mounted on the curvedsurface portion 682. That is, the decoration member 615 is aconfiguration for smoothly connecting the curved surface portion 682 andthe window 610 to each other. The curved surface portion 682 and thecurved portion 615 b may have the corresponding shapes so as to beengaged with each other.

Here, the decoration member 615, as illustrated in FIG. 16, is locatedon an upper portion of the touch sensor 620, and a printed circuit board650 is disposed between the frame 640 and the rear case 680. Also, acover portion 684 for covering a rear surface of the terminal main bodyis widely formed at one side of the accommodating portion 685.

Meanwhile, one embodiment of the present invention may have a problem inview of a connection of a flexible printed circuit board (FPCB) in casewhere side surfaces of a mobile terminal are curved.

FIG. 21 is a partial perspective view in case where a mobile terminal iscurved along a lengthwise direction thereof. As illustrated in FIG. 21,a window 10, a touch sensor 20 and a display 30 may all be curved in alengthwise direction (Y-direction) of the mobile terminal. Here, driveintegrated circuit (IC) chips 21 and 31 of the touch sensor 20 and thedisplay 30 are attached to lower ends of the touch sensor 20 and thedisplay 30, respectively, and connected to a printed circuit board (notillustrated) by FPCBs 25 and 35, respectively.

In such a manner, when the mobile terminal is curved in the lengthwisedirection, there is not a big problem in an arrangement space of thedrive IC chips 21 and 31. However, as illustrated in FIG. 22, when themobile terminal is curved in a widthwise direction (X-direction) of themobile terminal, there is a problem that portions to which the driver ICchips 21 and 31 are attached cannot be curved. That is, if the window 10is divided into a central region 10 b and both side surfaces 10 a and 10c, the window 10 may merely be curved at the both side surfaces 10 a and10 c, failing to be curved at the central region 10 b.

However, as illustrated in FIG. 23, if the driver IC chips 21 and 31 andthe FPCBs 25 and 35 are arranged on the side surface of the mobileterminal, the mobile terminal can be fully curved in the widthwisedirection thereof.

The present invention, as illustrated in FIG. 23, relates to a mobileterminal which is capable of being curved partially or entirely in awidthwise direction thereof by arranging FPCBs on a side surface of themobile terminal.

Hereinafter, a configuration therefor will be explained.

As aforementioned, FIG. 5 is the exploded perspective view of the mobileterminal 300 in accordance with the first exemplary embodiment disclosedherein, FIG. 6 is the partially-exploded perspective view of FIG. 5, andFIG. 7 is the sectional view taken along the lines AA, BB and CC of FIG.5. Hereinafter, a fifth exemplary embodiment will be described withreference to FIGS. 5 to 7. That is, the fifth exemplary embodiment isrelated to the first exemplary embodiment.

First, a mobile terminal 300 according to the fifth exemplary embodimentincludes a main body having front and side surfaces, a display module301 disposed on a top of the main body and curved from the front surfaceto the side surfaces to define at least parts of the side surfaces, aframe 340 disposed on a rear surface of the display module 301 andhaving a shape corresponding to the display module 301 to support thedisplay module 301, a rear case 380 covering a rear surface of the mainbody, a PCB 350 located between the frame 340 and the rear case 380, andan FPCB 360 having one end connected to a side surface of the displaymodule 301 and the other end electrically connected to the PCB 350.

Here, the FPCB 360 may be connected to the PCB 350 in a manner ofbypassing the frame 340 (see the fifth exemplary embodiment) orpenetrating through the frame 340 (see a sixth exemplary embodiment).

Here, the frame 340 includes a front surface portion 341 facing thefront surface of the mobile terminal and having a flat or curvedsurface, and a side surface portion 342 extending from the front surfaceportion 341 toward the side surface of the mobile terminal so as todefine at least a part of the side surface. The side surface portion 342is formed to be almost perpendicular to the front surface portion 341,and can have a curved section exceeding 90°, unlike the window 310. Theshapes of the front surface portion 341 and the side surface portion 342are also applied equally to the display module 301, and also to thesixth exemplary embodiment to be explained later.

Here, the touch sensor 320 and the display 330 are curved to correspondto the curved shape of the window 310. When the front surface portion341 of the frame 340 is curved, the display 330, the touch sensor 320and the window 310 are curved accordingly. The PCB 350 is locatedbeneath the frame 340 so as to perform a function of the controller 180.

The window 310, 410 in one embodiment disclosed herein is implemented asa single window. The touch sensor 320, 420 is located between the window310, 410 and the display 330, 430 to sense a touch input applied to thewindow 310, 410.

One embodiment disclosed herein may allow for an integral structure ofthe display 330 disposed on the upper surface of the frame 340 andcurved from the front surface toward the side surface, the touch sensor320 disposed on the upper surface of the display 330 and curved alongthe shape of the display 330 to form at least the part of the sidesurface, and the window 310 disposed on the upper surface of the touchsensor 320 to form the appearance of the mobile terminal. That is, thedisplay 330, the touch sensor 320 and the window 310 may be thecomponents of the display module 301. This is equally applied to thesixth exemplary embodiment to be explained later.

As illustrated in FIG. 5, the supporting members 370 are disposed atboth sides in the lengthwise direction of the mobile terminal 300between the frame 340 and the rear case 380, to support lower portionsof the display module 301 and the side surface portions 342 of the frame340. Each of the supporting members 370 includes a vertical portion 371that connects the window 310 and the rear case 380 so as to define atleast a part of the appearance of the mobile terminal 300, and comes incontact with the window 310, and a horizontal portion 372 thataccommodates thereon the touch sensor 320, the display 330 and the frame340.

Here, since each supporting member 370 defines the part of theappearance of the mobile terminal 300, the supporting member 370 mayhave a smoothly curved surface from a portion contacting the window 310to portion contacting the rear case 380. That is, that the verticalportion 371 and the horizontal portion 372 are perpendicular to eachother merely indicates that portions thereof forming a space formounting the touch sensor 320, the display 330 and the frame 340 areapproximately perpendicular to each other, but does not indicate thatthe entire supporting member 370 is exactly formed in the perpendicularshape.

An accommodation groove 375 in which the FPCB 360 is mounted is formedalong the vertical portion 371 and the horizontal portion 372. Theaccommodation groove 375, as illustrated in FIGS. 6A and 6B, includes afirst part 375 a recessed into the vertical portion 371, and a secondpart 375 b formed perpendicular to the first part 375 a and recessedinto the horizontal portion 372. Here, a sidewall 375 c which protrudesfrom the second part 375 b and has a step corresponding to a height ofthe horizontal portion 372 is formed.

Meanwhile, the FPCB 360 includes a first vertical portion 360 a that isaccommodated in the first part 375 a and connected to an end of thedisplay module 301, a first horizontal portion 360 b thatperpendicularly extends from the first vertical portion 360 a and isaccommodated in the second part 375 b, a second vertical portion 360 cthat extends from the first horizontal portion 360 b and is upwardlyformed along the sidewall 375 c, and a second horizontal portion 360 dthat extends from the second vertical portion 360 c over theaccommodating groove 375 so as to be connected to the PCB 350. Here, theFPCB 360 includes a first FPCB 361 that is connected to the touch sensor320 and the PCB 350 to realize a touch function, and a second FPCB 362that is connected to the display 330 and the PCB 350 to represent imageinformation. The first FPCB 361 and the second FPCB 362 have the sameshape and overlap each other.

Lower end portions of the frame 340, the touch sensor 320 and thedisplay 330 are placed on the first horizontal portion 360 b. That is,when the display module 301 and the frame 340 are coupled to thesupporting member 370, the FPCB 360 is pressed. Here, the FPCB 360 andthe PCB 350 may be connected to each other by a connector 365 (see FIG.7C).

Meanwhile, the horizontal portion 372 is provided with a first throughhole 373, in which a first protrusion 343 formed on an edge of the lowerend of the frame 340 and a second protrusion 381 protruding from an edgeof an upper surface of the rear case 380 are inserted. Referring to FIG.7B, it can be understood that the first through hole 373 is formed inplural through the horizontal portion 372 of the supporting member 370,and both of the first protrusion 343 protruding from the lower end ofthe frame 340 and the second protrusion 381 protruding from the uppersurface of the rear case 380 are simultaneously inserted into each firstthrough hole 373.

In such a manner, the frame 340 and the rear case 380 are engaged withthe supporting member 370 in the manner that both of the firstprotrusion 343 and the second protrusion 381 are simultaneously into thesingle through hole 373 in a closely-adhered state. FIG. 7B is asectional view taken along the line BB of FIG. 5, which shows that thefirst protrusion 343 is formed more outside than the second protrusion381. The first protrusion 343 is as high as the first through hole 373formed through the horizontal portion 372.

FIG. 7C is a sectional view taken along the line CC of FIG. 5. The FPCB360 is connected to ends of the touch sensor 320 and the display 330 tobe mounted in the accommodation groove 375 formed at the supportingmember 370, and connected to the PCB 350 by the connector 365.

Here, the window 310 is formed along the side surface of the mobileterminal to be shorter than the touch sensor 320 and the display 330. Inthis instance, the part shorter than the touch sensor 320 and thedisplay 330 is supplemented by the supporting member 370. This may allowthe touch sensor 320 and the display 330 to be stably mounted on thesupporting member 370 together with the window 310.

Hereinafter, a mobile terminal 400 according to a sixth exemplaryembodiment disclosed herein will be described. In the followingvariation or embodiment, the same/like reference numerals are given tothe same/like components to the foregoing embodiments, and descriptionthereof will be omitted.

The fifth exemplary embodiment has illustrated that the shorter part ofthe window 310 is supplemented by the separate members, namely, thesupporting members 370, but the sixth exemplary embodiment illustratesthat the mold members 415 (i.e., glass-inserted molds) are formed at anend of the window 410 through an insert-injection molding operation.Each of the mold members 415 is formed along a lengthwise direction ofthe mobile terminal 400. The sixth exemplary embodiment is substantiallysimilar or the same to the fifth exemplary embodiment, except forreplacing the supporting member 370 with the mold member 415. Thus,detailed description of he similar configurations will be omitted.

In the sixth exemplary embodiment, a second through hole 445 is formedthrough a side surface portion 442 of a frame 440 to connect an FPCB 460and a PCB 450 to each other. The FPCB 460 is electrically connected tothe PCB 450 through the second through hole 445. An edge portion 443protrudes from a lower end of the side surface portion 442 of the frame440 in a horizontal direction. A third protrusion 481 is formed at anedge of an upper surface of a rear case 480 covering the frame 440 andbrought into contact with an inner side of the side surface portion 442of the frame 440.

That is, the frame 440 in the sixth exemplary embodiment, similar to thefifth exemplary embodiment, includes a front surface portion 441 thatfaces a front surface of the mobile terminal 400 and has a flat orcurved surface, a side surface portion 442 that extends from the frontsurface portion 441 and is curved toward a side surface of the mobileterminal 400, and an edge portion 443 that outwardly protrudes from theside surface portion 442 in a horizontal direction so as to define amounting space of the display module 301.

FIG. 10A is a sectional view taken along the line AA of FIG. 8. Asillustrated in FIG. 10A, side end portions of the mold member 415, thetouch sensor 420 and the display 430 are mounted on the edge portion443, and the third protrusion 481 allows the frame 440 to be more firmlycoupled to the rear case 480. FIG. 10B is a sectional view taken alongthe line BB of FIG. 8. It can be seen more obviously in FIG. 10B thatthe mold member 415, the touch sensor 420 and the display 430 aremounted on the edge portion 443 at a portion without the thirdprotrusion 481 formed. FIG. 10C is a sectional view taken along the lineCC of FIG. 10. As illustrated in FIG. 10C, the FPCB 460 is connected toends of the touch sensor 420 and the display 430, and connected to thePCB 450 by a connector 465 through the second through hole 445 formed atthe frame 440.

Here, a width of the edge portion 443 is the same as that of a displaymodule 401.

The window 310, 410, the touch sensor 320, 420, the display 330, 430 andthe frame 340, 440 may be integrated together so as to be configured asone display module 301, 401.
